I talked last week (April 18th) and gave a demo of using solder stencils to make surface mount PCBs and promised to...
Well we're starting up for the year - in fact we've already sort of started with regular Thursday and Saturday open work...
We spent tonight doing a guided build. We had two goals: 1) Learn how to take 3D pictures with one camera and the o...
For those of you that don't regularly read the mailing list, Paul posted recently on the schedule over Christmas and New Years time of the year. There's a lot of people heading out of town, spending time with family they don't see often, or just plain busy - so the workshop won't be open as regularly. There will be the odd event on Thursday night, and the workshop will sometimes be open on Saturdays. Check the calendar and the mailing list for details on specific dates. If you are interested in using the space please send mail to the mailing list and we'll see which board members are availaContinue ReadingView Comments (1)
Here are some notes on my book-scanner project, inspired by diybookscanner.org. This is a work in progress and will initially be a single large page and I'll probably update it and split it into a Lessons Learned (blind alleys, problems, workarounds and eventual solutions) section at some point. If you want something I haven't documented yet just email me: email@example.com Vision I am planning on building a book-scanner using 3d printed parts so that the design can be easily replicated in the near future when hobbyist 3d printing becomes more widespread. I want something thatContinue ReadingView Comments (7)
I've started giving a series of basic electronics courses at Makerspace - these are aimed at everyone including complete beginners - I'm avoiding maths as much as possible, the idea is to get an understanding of what's going on in a circuit without getting bogged down in the details - your goal should be to be able to look at a schematic, ask yourself "what's that thing for?" and be able to make a reasonable guess I'm making heavy use of the excellent circuit simulations at http://www.falstad.com/circuit/e-index.html - your browser will need java enabled to use them. The first sessionContinue ReadingLeave a Comment
I've finally uploaded the PDF of the slides I was using. Note the static image on the page about how the Microsoft Kinect gets depth information from the changes in how the dots are perturbed by objects. This was originally an animated gif. You can go to the original source for that if you like. Click here for the original blog post I got this animated gif from.Continue ReadingView Comments (1)
OpenWRT: thats an odd name... The story starts late 2002 when Linksys released a wireless router called the WRT54G. Andrew Miklas noticed (from the visible names used in the internal filesystem, amongst other things) that it was using Linux, without in any way acknowledging this or making the source available. They had obvioulsy modified Linux to get it to run on their hardware. This is a violation of the Linux license, the GPL. He tried contacting Linksys who weren't immediately co-operative, so he posted to the Linux Kernel mailing list and Linksys came under considerable pressure to rContinue ReadingLeave a Comment
Here's some references from the 3D printing talk: First of all Thingiverse where you can find 1000s of things to build and make http://www.thingiverse.com/ ---------------------------------------------------------------- The "reprap host" slicing application can be downloaded from reprap.org http://www.reprap.org/wiki/Installing_RepRap_on_your_computer you'll need a working Java runtime to use it. You need to download the config file for our working reprap from: http://www.taniwha.com/~paul/reprap.properties install it in ~/.reprap (or wherever else reprap host stores sContinue ReadingLeave a Comment
As announced at last night's meeting we're having a competition: Clothesline Racing The basic idea is to build a device that will travel from one end of a clothesline to the other and back again - there will be (chocolate) fishy prizes. The clothesline will be strung outside, as level as we can and fairly taut - but will probably dip a little in the middle. The rules we'll be using will be the same as those listed below: http://www.tcmaker.org/blog/2010/10/clothesline-race-o-rama-mk2-sat-nov-20-2010/ with some minor (largely metric) changes - we'll have a 30m line (if we can find sContinue ReadingLeave a Comment
